£1.20 + (1/4 * £1.20)
= £1.20 + £0.30
= £1.50
Answer:
$4.25
Step-by-step explanation:
4 quarters is 1 dollar
1 nickel is 5 cent
14 divided by 4 = 3.5
3.5 + 5 times 5 = $4.25

Answer:
1 cm
Step-by-step explanation:
We know that the formula for perimeter is<u> 2(l+w) or l+l+w+w</u>
We know that the height is 5 cm so that means <em><u>w= 5</u></em> also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is <em><u>1 cm</u></em> if you add the length together you 2 when you add the width you get 10. <em>10+2=12.</em>
Answer:
3.5
Step-by-step explanation:
The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4
We have the Logarithmic equation
pH=-log [H3O+],
We have the hydronium ion concentration = 3.2 x 10^-4
Hence,
pH = - log[3.2 × 10 ^-4]
pH = 3.4948500217
Approximately
pH = 3.5
Therefore, the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4 is 3.5
